A method is provided for controlling a vehicle battery system comprising a voltage bus having positive and negative bus rails, at least one battery pack connected to the voltage bus and having positive and negative battery terminals, and a battery disconnect unit. The method includes performing a first battery disconnect process when an event condition is detected, and performing a second battery disconnect process when a high overcurrent condition is detected, and disconnecting the at least one battery pack from the voltage bus via the battery disconnect unit by performing a third battery disconnect process when a low overcurrent condition is detected. The first battery disconnection process utilizes disconnection of a main explosion fuse, the second battery disconnection process utilizes one or more of a thermal fuse, a solid state relay, and/or a current sensor, and the third battery disconnection process utilizes one or more contactors or solid state relays.

    提供了一种用于控制载具电池系统的方法,所述载具电池系统包括具有正和负总线轨的电压总线、连接到所述电压总线并且具有正和负电池端子的至少一个电池组、以及电池断连单元。所述方法包括:通过在检测到事件状况时执行第一电池断连过程、通过在检测到高过电流状况时执行第二电池断连过程、以及通过在检测到低过电流状况时执行第三电池断连过程来经由所述电池断连单元将所述至少一个电池组从所述电压总线断连。第一电池断连过程利用断开主要爆炸熔丝,第二电池断连过程利用热熔丝、固态继电器和/或电流传感器中的一个或多个,并且第三电池断连过程利用一个或多个接触器或固态继电器。
